Propeller Race Car

This project has students design a vehicle, print it out, and then test it. They are given a motor, wires, 9 volt battery, a switch, and 2 axles. Before this project we went over soldering and electrical circuits so they can wire their cars. I usually let them print out a few sets of wheels and propellers so they can test them, but they can only print out one car body so they have to make sure their measurements are good before printing.
